Function hexStringOfArray

convert an array of integer numbers to hex-string, for the sake of easing representation, or for visual purposes.

to customize the apearance of the hex-string, or to use a different radix, use the HexStringReprConfig interface to change the default options.

you must make sure that every element of your array arr is non-negative, in addition to being less than options.radix ** 2. since the default options.radix === 16, each of your number must be smaller than 256 on the default config.

to invert the operation of this function (i.e. parse an array of integers from a string), use the hexStringToArray function with the same config options.

import { assertEquals as assertEq } from "jsr:@std/assert"

const
	my_binary_code = [1, 2, 3, 125, 126, 127, 192, 225, 255],
	my_custom_config: Partial<HexStringReprConfig> = {
		sep: ",",
		trailingSep: true,
		bra: "<",
		ket: ">",
	}

const my_binary_code_repr = hexStringOfArray(my_binary_code, my_custom_config)

assertEq(my_binary_code_repr, "<0x01,0x02,0x03,0x7D,0x7E,0x7F,0xC0,0xE1,0xFF,>")
